- Level
- L3 — Infrastructure engineer
- Duration
- 4 h
- Maintainer

Learning objectives
- 01Establish an end-to-end IBC link
- 02Measure latency, cost and failure rate
- 03Document behaviour when the link breaks
Guided lab
Connect two cohort Cosmos chains and run a hundred measured transfers.
Independent lab
Break the link mid-transfer and document the exact state of the funds.
Security angle
Client expiry and stranded funds: the two failure modes to understand before going live.
Assessment
Measurement record over a hundred transfers, with failure analysis.
